Never disconnect the control cable between the display unit and the control unit while the unit is powered up. Electrical damage could occur to either/both units.
Electrostatic discharge (ESD) is a persistent nemesis for any piece of electronic equipment, therefore efforts should be made to keep ESD to a minimum, as damage or degradation will occur to the device itself.
Efforts should be made prior to installation to minimize ESD and power fluctuations, and controllers/monitors should always be properly grounded.
Always use the transformer provided with the device and never try to use one transformer to power both the controller and an electric actuator.
Never use the supplied transformer to power more than one controller. Splitting the current between these two devices will result in damage to the actuator, the transformer and controller. Consult the manuals for each of these devices prior to installation for proper wiring techniques.
FMS Installation Tips
Seal off the space prior to checking the calibration of a room pressure monitor by making sure all doors and windows are closed prior to validating the pressure reading. Silicon seal around both walls’ pressure sensor input plates during installation.
HMS Installation Tips
The sensor must be located in a position that is least affected by turbulent air within the hood. With either type of fume hood arrangement, the sensor is best located approximately six inches back from the vertical sash track. There are two types of fume hood arrangements which need to be considered: By-Pass and Non-By-Pass.
By-Pass – Locate the sensor vertically in the center of the region between the bottom of the sash in the fully open position and the bottom edge of the by-pass opening.
Non-By-Pass – Locate the sensor vertically six inches above the bottom of the sash in the fully open position.
Be certain that the flow sensor reference port is in laboratory room air. Apply silicone sealant around the sensor immediately prior to mounting the assembly to its mounting surface. Be careful to avoid getting sealant in the sensor port.
